[ i J Tip s
If the climate control system is operating in cool ing mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
out lets completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use t he a ir conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the a ir co nditioner only when necessary. Also please
note the follow ing po ints:
- If you want to save fuel, activate ECON.
If you are going to drive with the windows open, use ECON.
W For the s ake of the environm ent
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air. •
Applies to v ehicl es: with so lar slidi ng /tilt ing sunr oof
Solar blower fan /solar roof
With sufficient sunlight, the blower fan continues to
operate with solar energy to bring in fresh air after the
ignition has been switched off.
T he fan motor is operated by solar energy through the solar roof
after the igni tion is turned off. P lease make certa in that
vents ©
and© are open to achieve optimal ventilation ~ page 122, fig. 137 .
Controls a nd eq uip­
ment
The ventilation operates only with the sunroof c losed or in the tilted
position.
If the vehicle was switched off in the recirculation mode, the air
conditioning automatica lly switches to fresh air operation .

ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or
dehumidified.
If the vehicle interior becomes too hot or if the windows fog up,
ECON mode should be turned off. As soon as the
(AUTO ] button in
the air conditioning controls is pressed, the system automatically leaves the ECON mode, and the air conditioning compressor is
tu rned on again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system
detects polluted outside air, the sensor decides whether the air
pollution can be reduced by the factory-installed pollutant filter or
whether it is necessary to switch to air recirculation . W ith heavy
concentrations of pollutants, the air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. As soon as the concentration of pollutants in

Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position => &.
- Switch off the engine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed
downhill, turn the front wheels
toward the curb.
- If you are parking headed
uphill, turn the front wheels
awayfrom the curb.
- Move the selector lever into the
P position.
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
Controls and equip­ ment
&, WARNING (continued)
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain
in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs . Parking barriers and curbs vary in
height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb.
• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstacles, for which the
vehicle is not designed , because components of the vehicle close to
the ground, such as bumper covers, spoilers and suspension and
exhaust system components, may become damaged. •

T he transmission is self adapting and wi ll autom ati ca lly select the
best shift program suited to t he driving condi tions and drivi ng s tyle.
The transmission will se lect one of the
eco nom y programs when
you drive at a steady speed or a gradual ly changing speed without
heavy acce leration . T his achieves optimum fuel efficiency, with ear ly
upshifting and delayed downshifting .
T he trans mission wil l automat ica lly select the
s porty shift programs
when you drive at higher speeds, or with heavy acce leration and
frequen tly changing speeds . Upshifts are de layed to make full use
of engine power. Down shifting takes place at higher engine speeds
t han in the economy programs .
The selection of the most suitab le shift program is a continuous,
automatic process . The driver can also make the transmission
switch to a sporty program by
quickl y pressing down the gas peda l.
T his causes the transmission to shift down to a lower gear to
achieve rapid acceleration, e.g . for quickly passing ano ther veh ic le .
You do not need to press the gas pedal into the kick-down range .
After the transmission has upshifted, t he original program is
selected according to your driving style.
An additional shift program allows the automatic transmission to select the proper gear for uph ill and downh ill gradients.
T his prevents the transmission from upshifting and downshifting
unnecessa rily on hi lls. The transmiss ion will shift down to a lower

To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into
gears
1, 2, 3, 4 or 5 before the engine reaches its maximum RPM.
If you apply a light thrott le when accelerating, tiptronic® will auto ­
matically shift from 1st to 2nd gear to save fuel. If you app ly a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the driver shifts into 2nd gear.
If you take your foot off the accelerator peda l when driving down a
steep inc line, tiptronic® wi ll downshift from the selected gear into
the next lower gear until it reaches 1st gear, based on road speed
and engine RPM. Automatic downshifting is interrupted as soon as
you apply the throttle again.
[ i ] Tips
• When you shift into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine.
• When the kickdown comes on, the transmission will shift down
to a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic® is inoperative when the transmission is in the fai l-safe
mode .•

Chassis Controls
Four different driving modes can be set by the driver.
The automatic control processes are speed -and time -dependent.
For example, it is not possible to raise the suspension to the lift
mode above certain speeds .
When a speed of about 75 mph (120 km/h) is exceeded for more than 30 seconds, the vehicle is automatically lowered approximate ly 1
inch (25 mm) to a level suitable for highway speeds, except in the
standard mode . Road holding is optim ized as a result of the lower
center of gravity and fuel consumption is reduced as a result of
reduced wind resistance .
